Steps to reproduce the bug

1. Select some files
2. Tap the 'Rename' button
3. Type the new name template, including a / (not as the last character)
4. Tap 'OK' to rename
5. Grant permission to handle files (this does not happen every time)

Expected behavior

The files are renamed

Actual behavior

Two (apparently random) outcomes:

• Only one of the files remain, and its new name is just the part of the pattern after /. All the other files are permanently deleted.

• An exception/unknown error message appears. After a refresh, all the files are permanently gone.

To add a few more details: Using the simple renaming method, the app correctly displays a toast message The name contains invalid characters when the string contains /.
Using the pattern method, the app, however, displays an error message:

After cancelling the dialog and refreshing the file list all but one of the files to be renamed have disappeared.

(Tested on devices with Android 9 and Android 14.)
